They stole back to their spring, and they sank down below its clear surface. Then came Hylas singing a song that he had heard from his mother. He bent down to the spring, and the brimming water flowed into the sounding bronze of the pitcher. Then hands came out of the water. One of the nymphs caught Hylas by the elbow; another put her arms around his neck, another took the hand that held the vessel of bronze. The pitcher sank down to the depths of the spring. The hands of the nymphs clasped Hylas tighter, tighter; the water bubbled around him as they drew him down. Down, down they drew him, and into the cold and glimmering cave where they live. There Hylas stayed. But although the nymphs kissed him and sang to him, and showed him lovely things, Hylas was not content to be there. Where the Argonauts were the fires burned, the moon arose, and still Hylas did not return. Then they began to fear lest a wild beast had destroyed the boy. One went to Heracles and told him that young Hylas had not come back, and that they were fearful for him. Heracles flung down the pine tree that he was fashioning into an oar, and he dashed along the way that Hylas had gone as if a gadfly were stinging him. "Hylas, Hylas," he cried. But Hylas, in the cold and glimmering cave that the nymphs had drawn him into, did not hear the call of his friend Heracles. All the Argonauts went searching, calling as they went through the island, "Hylas, Hylas, Hylas!" But only their own calls came back to them. The morning star came up, and Tiphys, the steersman, called to them from the Argo. And when they came to the ship Tiphys told them that they would have to go aboard and make ready to sail from that place. They called to Heracles, and Heracles at last came down to the ship. They spoke to him, saying that they would have to sail away. Heracles would not go on board. "I will not leave this island," he said, "until I find young Hylas or learn what has happened to him." Then Jason arose to give the command to depart. But before the words were said Telamon stood up and faced him. "Jason," he said angrily, "you do not bid Heracles come on board, and you would have the Argo leave without him. You would leave Heracles here so that he may not be with us on the quest where his glory might overshadow your glory, Jason." Jason said no word, but he sat back on his bench with head bowed. And then, even as Telamon said these angry words, a strange figure rose up out of the waves of the sea. It was the figure of a man, wrinkled and old, with seaweed in his beard and his hair. There was a majesty about him, and the Argonauts all knew that this was one of the immortals--he was Nereus, the ancient one of the sea.
